Decision making under uncertainty in the alarm systems response

Abstract

Purpose The purpose of this paper is to develop an advanced decision-making support for the appropriate responding to critical alarms in the hazardous industrial facilities. Design/methodology/approach A fuzzy analytical hierarchy process is suggested by considering three alternatives and four criteria using triangular fuzzy numbers to handle the associated uncertainty. A logarithmic fuzzy preference programming (LFPP)-based nonlinear priority method is employed to analyze the suggested model. Findings A quantitative decision-making support is not only a necessity in responding to critical alarms but also easy to implement even in a relatively short reaction time. Confirmation may not be the appropriate option to deal with a critical alarm, even with the availability of the needed resources. Practical implications A situation related to a flammable gas alarm in a gas plant is treated using the developed model showing its practical efficiency and practicality. Originality/value The proposed model provides a rational, simple and holistic fuzzy multi criteria tool with a refined number of criteria and alternatives using an LFPP method to handle process alarms.

An effective decision-making method for building retrofit measures strategy

“…The Fuzzy Analytical Hierarchy Process (FAHP) is recognized as one of the widely adopted Multi-Criteria Decision-Making (MCDM) methods. 19,21,22,27 FAHP allows for the quantitative consideration of multiple criteria, facilitating the formulation of the decision problem and simultaneous ranking of Energy Efficient Retrofit Measures (EERMs).…”
